but as more I know more about Japanese culture, more I understand their limits in design and story-telling.

Limits? Their lack of limits you mean. The Japanese do not shy away from either telling a huge and overwhelming plot, or little plots with an incredible amount of detail. They pay more attention to characters and the viewer's ability to piece things together than blatantly explaining every tiny little detail behind a story as if you are an idiot. I like that you have to use your own imagination to make a story whatever you want it to be. Not only the story is clever this way, but it is respectful towards the viewer.
